Name: Pyridine-3-sulfonyl Chloride Chemical Formula: C5H4ClNO2S Synonyms: 3-Pyridinesulfonyl chloride Mol Wt: 177.61 g/mol Form: Usually found as a crystalline solid or powder Appearance: Pale yellow to off-white Odor: Sharp, somewhat unpleasant, chemical
Classification: Corrosive, Irritant Health Hazards: Causes skin burns and eye damage, may induce respiratory irritation Physical Hazards: Reacts with water and moisture, forming acid vapors Environment Hazards: Harmful to aquatic organisms Signal Word: Danger Pictograms: Corrosive, Exclamation Symptoms: Redness, pain, burns on contact, coughing or wheezing upon inhalation
Chemical: Pyridine-3-sulfonyl Chloride Chemical Identity: 98% or greater purity Impurities: Minor pyridine derivatives CAS Number: 16133-25-8
Inhalation: Move to fresh air immediately, assist breathing if necessary Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical help Symptoms to Watch: Persistent cough, breathing difficulty, severe skin or eye pain
Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam Unusual Dangers: Toxic gases like hydrogen chloride, sulfur oxides, and nitrogen oxides may form Firefighting Instructions: Wear chemical-resistant gear, self-contained breathing apparatus Special Precautions: Approach upwind, avoid inhaling smoke or vapors
Personal Protection: Put on chemical-resistant gloves, goggles, lab coat Spill Cleanup: Avoid breathing dust or vapors, use non-sparking tools, sweep up carefully Containment: Prevent entry to drains or water sources Disposal: Place collected material in clearly labeled, sealed containers Ventilation: Work in well-ventilated areas or fume hoods
Handling: Use with local exhaust, avoid creating dusts, keep away from moisture Storage: Keep container tightly sealed, store in cool, dry, well-ventilated place Segregation: Separate from acids, alcohols, water, oxidizing agents Precaution: Avoid direct physical contact, label storage clearly
Engineering Controls: Fume hoods or local exhaust Personal Protective Equipment: Protective gloves (nitrile), safety goggles, face shield Clothing: Long-sleeved, chemical-resistant clothing Respiratory Protection: Use approved respirators if airborne exposure is possible Hygiene: Avoid eating, drinking, or smoking in work areas
Physical State: Solid Color: Pale yellow or off-white Melting Point: Decomposes near 60-70°C Boiling Point: Decomposes Solubility: Reacts with water, sparingly soluble in organic solvents Vapor Pressure: Low at room temperature Odor: Characteristic sharp Flammability: Not classified as flammable, but can exacerbate fires
Chemical Stability: Stable under recommended storage; degrades with moisture Hazardous Reactions: Reacts with water to form corrosive and toxic gases Incompatible Materials: Water, strong bases, alcohols, strong oxidizers, amines Hazardous Decomposition Products: Hydrogen chloride, sulfur oxides, nitrogen oxides
Routes of Entry: Inhalation, skin and eye contact, ingestion Acutely Toxic Effects: Burns to skin and mucous membranes; respiratory irritation Chronic Effects: Prolonged exposure may result in respiratory tract damage Sensitization: Not well documented but possible with frequent exposure Long-Term Risks: Potential for dermatitis and respiratory conditions
Toxicity to Aquatic Life: Harmful, may cause damage even at low concentrations Persistence: Decomposes on contact with moist environments Bioaccumulation: Data limited, expected low potential Environmental Fate: Converts rapidly to more hazardous byproducts upon environmental release Precaution: Avoid discharge into drains, water sources, or soil
Waste Treatment: Collect in sealed, labeled containers suitable for corrosives Method: Incineration by licensed chemical waste disposal facility Do Not: Flush to sewer or regular trash Regulation: Comply with local, regional, and national hazardous waste guidelines
Proper Shipping Name: Pyridine-3-sulfonyl Chloride Hazard Class: 8 (Corrosive) Packing Group: II or III depending on quantity and concentration UN Number: 3261 for related sulfonyl chlorides Precautions: Keep in tightly sealed chemical containers, protected from moisture Special Provisions: Ensure labeling and paperwork meet legal transport standards
Classification: Subject to chemical safety and environmental regulations Requirements: Users must train staff in safe use and emergency procedures Labelling: GHS-compliant hazard and precautionary statements Reporting: Notify authorities of significant spills or release incidents
